Even when she was little, Meghan Markle knew how to steal the spotlight.
All eyes will be on the 36-year-old bride-to-be when she marries Prince Harry at St. George's Chapel on Saturday, but long before she met the royal or played Rachel Zane on Suits, Meghan seemed to be the center of attention in her own family.
With just three days to go before she becomes a royal herself, ET is exclusively revealing video footage of an adorable 4-year-old Meghan, growing up in the suburbs of Los Angeles.
In one of the home videos, which you can watch in the player above, a fearless Meghan can be seen doing somersaults in a preschool production, seemingly loving the attention from the crowd.
ET also spoke with Meghan's estranged half-sister, Samantha Grant. Although she has been vocal about not receiving an invite to the royal wedding, she still has fond memories of the two growing up together.
"We lived in a normal, little house in Woodland Hills, California," Samantha says. "[We'd go] to the beach because it wasn't far away and going to the duck pond, which is one of her favorite things to do. She went to a private elementary school and high school and then college. It was very normal."
When she wasn't practicing her acting skills or having playtime with friends, Meghan spent plenty of days on TV and movie sets with her father, Thomas Markle, according to royal expert Katie Nicholl.
"He was a very successful lighting director, an award-winning lighting director on famous TV shows like the sitcom Married With Children," she explains. "That was where Meghan spent many of her years as a child growing up and I think the TV bug got under her skin when she was watching that show being made."
"[And] Meghan is incredibly close to her mother, Doria Ragland," she adds. "Doria has always been Meghan's inspiration, and she has been the one who has guided Meghan through her career and through her life encouraged her and inspired her. I think that because Doria is so important in Meghan's life, she also has become quite important in Harry's life as well."
Earlier this month, ET also exclusively revealed video footage of Meghan's trips abroad, including travels through Spain, New Zealand and the U.K. Watch below, and be sure to keep up with all of ET's coverage of the royal wedding as we count down to May 19.
